Yes, this can be done with a little modification to either a) the holster or b) the guns trigger guard itself. Since the 1911's trigger guard is rounded and the 4.3 and 5.1 trigger guard is 'squared' (for lack of a better word); You can either sand down and round off the 4.3/5.1's trigger guard until it fits the holster, or modify the holster itself though I'm unsure on how exactly that would go about. But, if you'd rather not sand down anything and you've got some extra cash laying about then just buy a TaniKoba grip set from ILLusion here on the forums.
